Koito

What Koito does

Koito Manufacturing Co., Ltd. (小糸製作所) is a Tokyo-headquartered, publicly listed Tier 1 automotive lighting supplier founded in 1915 and listed on the Tokyo Stock Exchange (TYO: 7276). The company designs and manufactures automotive lighting equipment — headlamps (LED, halogen, ADB variants), rear combination lamps, fog lamps, high-mounted stop lamps, and side turn signal lamps — alongside aircraft interior/exterior lighting and electronic, hydraulic, and mechanical equipment for aerospace and marine customers. Koito operates as a vertically integrated "total supplier," controlling everything from light-source development through electronics, and holds the No. 1 global share in headlamps at approximately 20%, with consolidated group revenue of ¥947.61 billion in FY March 2026 across 21,507 employees and operations in five regions (Japan, Americas, Europe, China, Asia).

The company's technology core rests on proprietary opto-electronic architectures, anchored by approximately 3,400 patents. Koito commercialized the world's first LED headlamp in 2007, followed by the world-first mass-produced BladeScan® ADB in 2019 (using high-speed rotating blade mirrors and 12 LEDs to replicate the resolution of ~300 LEDs). In May 2026, Koito launched a High-Definition ADB system featuring 16,000 individually controlled micro-LEDs, equipped in Toyota's new Lexus ES. The January 2025 acquisition of Cepton, Inc. added LiDAR sensor technology and the ILLUMIERE™ indoor/outdoor moving-object detection platform to the portfolio, extending the company from a lighting-only player into ADAS-relevant sensing. Adjacent product extensions include Road Projection Lamps, Animation Lamps, and Communication Lamps that support vehicle-to-pedestrian signaling in future autonomous mobility.

Koito's business model is OEM-embedded B2B: it sells lighting systems directly to global vehicle and aircraft manufacturers under multi-year contracts, with the OEM channel representing roughly 70% of automotive lighting industry volume. Pricing is negotiated per OEM program and is not publicly disclosed. The customer base is anchored by Toyota (Lexus HD ADB), Honda, and Boeing (lighting and electronic equipment on the 737 and 777), with approximately 60% of sales generated outside Japan. Aerospace, marine LED, and aftermarket channels provide additional revenue diversification but remain secondary to the core OEM automotive franchise. Forward strategy emphasizes expanding sensing/ADAS content per vehicle via the Cepton platform and embedding Koito in next-generation ADAS architecture through co-development with Denso.
